Drinking water in Nettersheim
3 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
How to read the share of the parametric value
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 31/12/2019. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

Frequently asked questions about drinking water in Nettersheim
- How hard is the water in Nettersheim?
- Wasserverband Oleftal Hellenthal publishes a total hardness of 1,69 mmol/l for the supply zone 53925 Kall, WA Knoppen (Entnahmestelle: WA Knoppen Ausgang HB) — that corresponds to 9.5 °dH. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 25.03.2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Nettersheim?
- Wasserverband Oleftal Hellenthal publishes a nitrate value of 15 mg/l for the supply zone 53925 Kall, WA Knoppen (Entnahmestelle: WA Knoppen Ausgang HB). The statutory parametric value is 50 mg/l; the measured value represents 30 % of the parametric value. Basis: 25.03.2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Nettersheim?
- Wasserverband Oleftal Hellenthal. The values shown here come from the supply zone 53925 Kall, WA Knoppen (Entnahmestelle: WA Knoppen Ausgang HB) and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
